| geographical variation of mandible size and shape in the ryukyu wild pig (sus scrofa riukiuanus). | we measured adult mandibles of ryukyu wild pigs from amami-oshima, kakeroma, okinawa, ishigaki and iriomote islands. the size cline was not statistically recognized among the populations of nansei islands. the ishigaki population was significantly larger than iriomote one in mandible length. some measurement ratios indicated that the ramus is enlarged laterally and that the body of mandible is dorso-ventrally developed in ishigaki and iriomote populations. the amami-oshima mandibles were relativ ... | 1998 | 9492361 |
| multivariate analysis of mandible in the ryukyu wild pig (sus scrofa riukiuanus). | we measured adult mandibles of ryukyu wild pig (sus scrofa riukiuanus) from tokunoshima island and compared the osteometrical data with those from six nansei islands. the mandibles in tokunoshima island were larger than those from amami-oshima and okinawa islands in some measurements. we concluded that the size cline was not statistically recognized among populations. in the principal component analysis, the size cline was also denied, and the separation could be made among island populations in ... | 1998 | 9673945 |
| prehistoric introduction of domestic pigs onto the okinawa islands: ancient mitochondrial dna evidence. | ancient dnas of sus scrofa specimens excavated from archaeological sites on the okinawa islands were examined to clarify the genetic relationships among prehistoric sus scrofa, modern wild boars and domestic pigs inhabiting the ryukyu archipelago, the japanese islands, and the asian continent. we extracted remain dna from 161 bone specimens excavated from 12 archaeological sites on the okinawa islands and successfully amplified mitochondrial dna control region fragments from 33 of 161 specimens. ... | 2002 | 12107598 |
| survey of the antibody against japanese encephalitis virus in ryukyu wild boars (sus scrofa riukiuanus) in okinawa, japan. | serum specimens were collected from 99 wild boars in the northern area of the main okinawa island and from 27 wild boars on iriomote island in okinawa prefecture from 1997 to 2005. sera were tested for japanese encephalitis virus (jev) antibody by hemagglutination inhibition assay and igg enzyme-linked immunosorbent assay. sixty-four samples (64.6%) in the northern area and 1 sample (3.7%) from iriomote island were positive for the jev antibody. the difference in seroprevalence between the north ... | 2007 | 17881875 |
